The church of Saint-Martin et Sainte Anne in Macquigny is one of the most westerly fortified churches in the region, but is generally still considered to belong to the Thiérache.

The first Romanesque church was built here in the 12th century – mainly in white stone – when the village had an abbey. Two arcades from this church can still be recognised on the south wall, which are now bricked up, as well as the simple entrance portal. The date “1501” above the portal indicates that the Romanesque bell tower was converted into a fortified watchtower.

Mighty buttresses support the keep. Unique in Thiérache are the two watch towers attached to the corners of the keep and above the buttresses: they have two storeys, which are pierced by embrasures and separated by machicolations.

Another unusual feature is that the two watchtowers are connected by a gallery and the two huge buttresses of the façade by a small, steep roof. Beneath this roof there were further battlements and machicolations.

The polygonal choir – higher than the nave – was restored in 1754 and is also supported by mighty buttresses.

Inside, there is a 15th-century baptismal font, a 16th-century oak Christ and a series of stained glass windows by master glazier Carl Mauméjean dedicated to St Martin and St Anne.

The building is usually closed for free tours, but the municipal administration offers several guided tours from April to September.
